A liquid refrigerant mixture of Nitrogen(1), Methane(2) and Ethane (3) with composition {z1=0.15,z2=0.55,z3=0.30} and temperature T1 is throttled from a pressure P1=25 bar down to a pressure of P2=1bar and it is partially vaporized. The temperature of the refrigerant at the outlet of the throttling valve is Calculate the temperature [T1 of the liquid refrigerant at the inlet of the throttling valve. Express your answer in deg C and round your numerical result to a single decimal digit. Assume that the mixture follows the Peng-Robinson Equation of State with all Binary Interaction Parameters equal to zero. Use an initial guess for T1(o)=100C
